Marc, That is one beautiful set of plans there. All I can say is, WOW. Love the old vintage designs. Looking forward to watching this build. That short nose scares me. Built a Clancey Baby Bee once, it had a short nose. I had a brick of lead in the nose of that thing, and the battery directly below the motor. And I never really did get the CG forward to where it should have been.

Pics look properly rotated to me. At 50" span 1/4" sq longerons should be fine. You might be able to get away with 1/8" sq even. If adding an electric motor you might want to fill in the first three bays at the nose with 1/16" sheet depending on where your radio gear and batteries are to be located. You might even step up to 1/8" sheet under the heavy components...if this is going to be RC it needs to be moved to the RC section...

I drew these plans 42yrs ago....never built it. Now, with electric stuff....I should be able to do a "floater" old timer! 50" wingspan with a lifting tail.Question is, to keep it light and use a small RC outfit....do you fellows think the fuse should be of 1/4" balsa, and maybe balsa gussets at front end? Any thin sheet work?Or built as is, please excuse the90 degree picture...maybe admin can rotate it for me....I'm technodum..... Please comment....I haven't started yet.....just started buying balsa.....Marc
